About Hanko
Hanko provides a comprehensive, API-first authentication solution that is both open-source (AGPL) and FIDO2-certified. Developers can implement a full auth system covering everything from passkeys, magic links, and social logins to enterprise-grade SAML SSO and multi-factor authentication. The platform is designed for flexibility, offering both a fully managed cloud service (Hanko Cloud) and a self-hosted option for complete data ownership and control. Integration is streamlined through Hanko Elements (pre-built UI components) and a powerful Flow API for building custom user experiences. Hanko also offers a standalone Passkey API to integrate FIDO2-certified passkey infrastructure into existing systems and provides a white-label authenticator app.
